c)80 mm hg and 80 mm hg
d) 70 mm hg and 120 mm hg
​

Answer 1

Answer:

(a)120mm hg and 80mmhg

pls mark me as brainliest

Answer 2

Answer:

a).120 mm Hg and 80 mm Hg

Explanation:

The temporary rise in blood pressure during the contraction of the heart is called systolic pressure and the temporary fall in blood pressure during relaxation of the heart is called diastolic pressure. Blood pressure is expressed as the ratio of the systolic pressure over the diastolic pressure. For a healthy resting adult person, the average systolic/diastolic pressures are 120/80 mm Hg. Aorta is directly supplied by left ventricle thus, the blood pressure in aorta is highest during systole of left ventricle. During it, left ventricle contracts and pushes blood into aorta.

Hope this will help !!!!!!!
